Top 10 GreenTech or CleanTech Startups to Watch Out for in 2021

A glimpse on the top GreenTech or CleanTech startups to watch out for this year.

Today, the modern world is at a stalemate. Unsustainable development, the depletion of fossil fuels, and the growth of global warming have brought us to a point of catastrophe. Our only choice is to move towards a more sustainable way of life, and as a result, people, companies, and governments have been moving toward a cleaner and greener solution which is called as GreenTech or CleanTech startups.


Here is a list of the top 10 GreenTech or CleanTech startups to watch out for in 2021:


Zolar allows homeowners to design and configure a solar system in a few clicks online, with the aim of changing their energy usage to 100 percent green energy. Its online setup integrates seamlessly the complete photovoltaic system design, from planning to insurance and financing to final completion. After four years and €14 million in funding, the company is still going strong. Zolar has a good chance of democratizing the energy market.


Dryad Networks

Dryad Networks is a sustainable Internet of Things startup. Its goal is to create a large-scale Internet of Things network that will allow public and private forest owners to monitor, assess, and preserve the world’s largest and most remote forests. The startup’s primary focus is on creating a method for detecting wildfires at extremely early stages.


Photom Technologies

Photom Technologies is a start-up that provides autonomous solutions for Operation & Maintenance (O & M) to improve the performance of renewable energy plants. The company’s mission is to create groundbreaking products and solutions for renewable energy plants while also being a key player in India’s renewable energy market.



Northvolt is a company that owns and operates lithium-ion battery plants that produce batteries for electric vehicles. The company’s plants produce environmentally friendly batteries with a low carbon footprint and recycling technology that does not jeopardize vital ecosystems, allowing the auto industry to efficiently substitute fossil fuels with electricity.



Ecoligo uses an online platform to finance solar projects in developing markets. The platform serves as a crowd-investing platform for renewable energy initiatives, bridging the funding gap that prevents solar projects in developing countries from being realized. So far, the Berlin-based startup has launched its crowd-financed Solar-as-a-Service model in East and West Africa, Central America, and Southeast Asia.


Industrial Phycology

Industrial Phycology has created and trademarked a method that uses algae’s power to remove nutrients from the land using cutting-edge techniques and technologies. The system was developed specifically for agricultural, urban, and industrial use, as well as to meet the demands of wastewater workers for higher-quality wastes.



Cervest is a company that creates an AI-powered climate intelligence platform that quantifies asset-level risks around the world. The company’s platform provides users with free, collaborative, and autonomous resources to manage ‘asset-level’ climate protection by providing science-backed and quantified analysis of climatic extreme events on physical resources, allowing companies, governments, and farmers to respond to climate volatility.


SkyCool Systems 

Using radiative cooling as an advanced technology, SkyCool Systems has demonstrated that specifically designed optical films can enable this method to allow cooling during the day. These optical films are highly reflective to sunlight but release thermal radiation to the atmosphere with remarkable efficiency, allowing daytime operation during the hottest time of the day.



Tibber is the creator of an energy consumption management app that helps users manage their electricity consumption. Customers can easily switch their power provider as well as regulate the power in their homes through the company’s digital application, which tracks energy usage at homes and provides tips on how to both minimize utilization and guide it towards the times of the day when electricity is affordable.



CoInspect is a GreenTech company that aims to protect food and the environment. It develops technologies to ensure food protection and sustainability from farm-to-table, a method in which hotels and restaurants purchase fresh foods directly from local growers. To minimize waste, enhance protection, and cut refrigeration emissions, the company created IoT-driven 24/7 temperature monitoring sensors and mobile checklist apps. As a result, millions of people around the world are protected.
